I can't help there but Belle~ my dd was given the RIAS in 2nd grade with a FSIQ 140. Retested 6 months ago with the WISC, with scores all over the place due to her slow processing. It definately lowered her FSIQ but her GAI correlated exactly with her previous RIAS. Plus her verbal met the DYS criteria. Haven't applied yet though, waiting for Explore test results. Hopefully today.
